Abstract
An instructional aid (10) for enabling and assisting a person to emulate a predetermined movement such as a golf swing including an image/data capturing device (11) for scanning capturing and storing the image/data signals of the person's golf swing or movement, and a transceiver (14) for transmitting the image/data signals over a communications network (15) to a remote computer (17). The computer (16) contains a database (17) which stores in digital form image signals and bio-mechanical data of a number of preselected swings or movements. The computer (16) analyses the person's image/data signals against image/data of a preselected swing and generates in digital form further visual images/data signals which can be transformed so as to assist or enable a person to be able to emulate the preferred swing. The instructional aid may also be used for analysing or reporting on particular geographical regions or objects and provides a specialized presentation for development of that region or object from information stored in the computer database.

8 2. Description of the Prior Art:
10Markers are often used in places, such as along 11roadsides, where there is a likelihood that the mark will 12be struck or hit by a passing object. Because of the costs 13of replacing damaged markers, the markers are preferably 14constructed so that they can withstand the force imparted 15by passing objects without being severely damaged.
16Flexible posts have been constructed for instance, such as 17those shown in U.S. Patent No. 4,862,823, in which an 18elastomeric element connects a marker post to a base or 19support. This enables the post to bend relative to the 20base at the elastomeric element when struck. This 21minimizes the damage that would otherwise occur if the post 22was rigidly constructed.
24U.S. Patent 5,205,236 shows a flexible marker having 25a tubular marker post which mounts over a stiffener core.
26The stiffener core prevents the tubular post from deforming 27when struck and causes the marker to bend at the flexible 28element.

CA 021487~1 1998-02-19 SUMMARY OF THE lNv~NLION
A new impact resistant marker is provided which has a marker post that is easily removed and replaced from the marker assembly. The marker has a marker base which is adapted to be secured to the ground of other substructure. An elongated mountlng core having a longitudinal axis and a mounting end is made from a substantially rigid material. An elastomeric, flexible element is coupled at a first end to the base and at an opposite, second end to the mounting end of the mounting core so that the mounting core is flexibly coupled to the base. A marker post has an elongate cavity which is defined by a cavity wall having an aperture. The cavity wall may be made from substantially resilient material. The mounting core inserts into the cavity of the marker post and a retaining means extends through the aperture formed in the cavity wall when the marker post is inserted over the core.
Once mounted, the retaining means effectively secures the marker post to the mounting core. The mounting core causes the marker post to pivot at the flexible element, when struck, from an original position to a deflected position. The flexible element then restores the marker post to the original position after it is struck.
The retaining means may be formed as at least one retaining lug which is secured to and protrudes laterally outward from the side of the mounting core. The retaining lug may have an inclined surface which slopes from the side of the mounting core to facilitate insertion of the mounting core into the cavity. The retaining lug may also be provided with CA 021487~1 1998-02-19 a side camming surface which causes the cavity wall of the marker post to be deformed from an original configuration when the marker post is rotated about the longitudinal axis of the mounting core. This causes the aperture to be forced away from the retaining lugs so that the marker posts can be easily removed from the mounting core.

3 Referring to the figures, Figure 1 shows a roadway 4 marker 10 of the present invention, having a base 12 which is secured to a substructure 14, such as the ground. The 6 base 10 may have an anchoring member (not shown) which is 7 driven into the ground or may be flat on the bottom for 8 securing to asphalt or concrete by a suitable adhesive.
As shown in Figure 2, the base 12 has an upward 11 protruding mandrel 18 which extends from an upper surface 12 of the base 12. An elongate mounting core 22 having a 13 longitudinal axis is also shown in Figure 2. The mounting 14 core 22 has a lower mounting portion 24 and an upper marker portion 26. The mounting core 22 is formed from a solid, 16 substantially rigid piece of elastomeric material. The 17 mounting portion 24 and the lower end of the marker portion 18 26 both have an substantially elliptical cross sectional 19 shape (Figure 4) wherein the width has the greater dimension and the thickness has the smaller dimension. The 21 width of the mounting portion 24 is greater than the width 22 of the marker portion 26. A flat guard member 28 locates 23 between and separates the upper end of the mounting portion 24 24 from the lower end of the marker portion 26. The guard member 28 also has an elliptical shape and has a width 26 which is greater than the width of the mounting portion 24 27 and the marker portion 26.
29 The mounting core 22 is provided with a plurality of ribs or splines 30 which give the mounting core 22 31 structural rigidity. The marker portion 26 of the 32 mounting core 22 tapers from the elliptical shaped lower 33 end to a substantially flat upper end 32, as shown in 34 Figures 1 and 5.
2~ ~8751 1 Referring to Figures 2-4, the mounting core 22 is 2 provided with a pair of lugs 34 which extend laterally 3 outward from opposite sides of the marker portion 26. Each 4 of the lugs 34 has an inclined upper surface which slopes downward from the side of the marker portion 26. Each of 6 the lugs 34 terminates at an outer end 38. The outer ends 7 38 are spaced apart a distance greater than the width of 8 the marker portion 26. Each of the lugs 34 has a side g camming surface 40 which is a convex curved or arcuate surface which curves toward the outer most end 38. As 11 shown in Figure 4, the side camming surfaces 40 of the lugs 12 34 are located opposite from each other, on opposite sides 13 of the marker portion 26 of the mounting core 22. opposite 14 the side camming surface 40, on each lug 34, is a flat side portion 42 located in a plane parallel to the longitudinal 16 axis of the mounting core 22. The lower surface 43 of each 17 retaining lug 34 is inclined with the lower surface sloping 18 upward from the end 38 of the lug 34 to the marker portion 19 26 of the mounting core 22.
21 A tubular marker post 44 having an elongate central 22 opening or cavity 46 is formed from a substantially 23 resilient polymeric material. The central cavity 46 is 24 defined by a cavity wall 50 which is provided with a pair of apertures 48 located near the lower end and on opposite 26 sides of the tubular marker post 44. The apertures 48 27 extend through the walls 50 of the tubular marker post 44 28 and are elliptical or oval in shape with the longer 29 dimension being parallel to the longitudinal axis of the marker post 44. As shown in Figure 4, the tubular marker 31 post 44 has an elliptical or circular cross section. When 32 the marker post 44 is mounted to the mounting core 22, the 33 retaining lugs 34 are received within the apertures 48.
34 This effectively secures the marker post 44 to the mounting core 22.
21487~1 1As shown in Figure 2, a flexible elastomeric sleeve s2 2having a lower end 54 and an upper end 56 is provided with 3an opening 58 (Figure 5). The opening 58 in the flexible 4sleeve 52 is configured to closely receive the mandrel 18 5of the base 12 and mounting portion 24 of the mounting core 622, vith the upper end 56 of the sleeve 52 receiving the 7mounting portion 24 of the mounting core 22 and the lower 8end 54 of the sleeve 52 receiving the mandrel 18 of the 9base 12. Fasteners 60, such as rivets or bolts, are used 10to secure the lower end 54 of the flexible sleeve 52 to the 11mandrel 18. The fasteners 60 are inserted through holes 62 12and 64 in the sleeve 52 and mandrel 18, respectively.
13Likewise, fasteners 66 are inserted through holes 68, 70 in 14the sleeve 52 and mounting core 22 to secure the upper end 1556 of the sleeve 52 to the mounting portion 24 of the 16mounting core 22. As shown in Figure 2, a clearance 74 17exists between the lower end of mounting portion 24 and the 18upper end of the mandrel 18. The mounting core 22 is thus 19flexibly coupled to the base 12.
21The marker post 44 is mounted to the mounting core 22 22as follows. With the marker post 44 initially removed from 23the mounting core 22, the lower end of the marker post 44 24is positioned over the upper end 32 of the mounting core 22 25with the longitudinal axis of the marker post 44 being 26substantially parallel to the longitudinal axis of the 27mounting core 22. The mar~er post 44 is then lowered so 28that the mounting core 22 inserts into the central cavity 2946 of the tubular marker post 44. As the marker post 44 is 30lowered, the lower end of the marker post 44 contacts the 31inclined upper surfaces 36 of the lugs 34 so that the 32cavity wall 50 of the marker post deforms from its initial 33configuration and expands over the lugs 34. The marker 34post 44 should be oriented so that the apertures 48 are 35aligned with the lugs 34 when the marker post 44 is lowered 21 1~7~1 1over the mounting core 22 so that they are received within 2the apertures 48 in the cavity wall 50 of the marker post 344. When this occurs, the lower portion of the marker post 444 is restored to its initial configuration with the lower 5end of the marker post 44 resting on or adjacent to the 6guard member 28 which divides the mounting portion 44 from 7the marker portion 26. The marker post 44 is thus 8effectively secured to the mounting core 22. If the 9tubular marker post 44 is pulled upward along lines 10generally parallel with the longitudinal axis of the 11mounting core 22, the inclined lower surface 43 of the 12retaining lugs 34 will contact the lower edges of the 13apertures 48 preventing dewunting of the marker post 44.
16When the marker post 4~ is struck, the marker post 44 17and mounting core 22 pivot from their original position at 18the flexible element 52 to a deflected position, as shown 19by the dashed lines in Figure 1. The mounting core 22 20gives the marker post 44 a desired stiffness so that the 21marker 10 bends at the flexible sleeve 52, approximately at 22the clearance 74, instead of deforming the marker post 44.
23The flexible element 52 then restores the mounting core 22 24and marker post 44 to their original upright or undeflected 25position.
27To remove the marker post 44, the lower end of the 28marker post 44 is rotated around the longitudinal axis of 29the mounting core 22. This causes the side edges of the 30apertures 48 in the cavity wall 50 of the marker post 44 to 31slide along the side camminq surface 40 of each of the 32retaining lugs 34. The camming surface 40 of the retaining 33lugs 34 causes the cavity wall 50 of the marker post 44 to 34be deformed so that the apertures 48 are forced away from 35the retaining lugs 34 and the ends 38 of the lugs 34 locate ~8751 ') 1 within the interior of the cavity wall 50. The marker post 2 44 is pulled and slipped off the mounting core 22. A new 3 marker post can then be mounted over the mounting core 22 4 as previously described.
6 The marker of the invention has several advantages.
7 The marker is flexible so that when struck it may bend, 8 thereby reducing any damage that would otherwise occur to 9 the mark post or marker post assembly. The lugs on the mounting core allow for a marker post to be easily 11 positioned and mounted to the mounting core by merely 12 inserting the mounting core into the marker post so that 13 the retaining lugs protrude through the apertures in the 14 marker post. The marker post is easily removed from the mounting core by merely twisting the lower end of the 16 marker post and pulling the marker post from the mounting 17 core.
19 While the invention has been shown in only one of its forms, it should be apparent to those skilled in the art 21 that it is not so limited, but it is susceptible to various 22 changes without departing from the scope of the invention.

The 6 base 10 may have an anchoring member (not shown) which is 7 driven into the ground or may be flat on the bottom for 8 securing to asphalt or concrete by a suitable adhesive.
As shown in Figure 2, the base 12 has an upward 11 protruding mandrel 18 which extends from an upper surface 12 of the base 12. An elongate mounting core 22 having a 13 longitudinal axis is also shown in Figure 2. The mounting 14 core 22 has a lower mounting portion 24 and an upper marker portion 26. The mounting core 22 is formed from a solid, 16 substantially rigid piece of elastomeric material. The 17 mounting portion 24 and the lower end of the marker portion 18 26 both have an substantially elliptical cross sectional 19 shape (Figure 4) wherein the width has the greater dimension and the thickness has the smaller dimension. The 21 width of the mounting portion 24 is greater than the width 22 of the marker portion 26. A flat guard member 28 locates 23 between and separates the upper end of the mounting portion 24 24 from the lower end of the marker portion 26. The guard member 28 also has an elliptical shape and has a width 26 which is greater than the width of the mounting portion 24 27 and the marker portion 26.
29 The mounting core 22 is provided with a plurality of ribs or splines 30 which give the mounting core 22 31 structural rigidity. The marker portion 26 of the 32 mounting core 22 tapers from the elliptical shaped lower 33 end to a substantially flat upper end 32, as shown in 34 Figures 1 and 5.
2~ ~8751 1 Referring to Figures 2-4, the mounting core 22 is 2 provided with a pair of lugs 34 which extend laterally 3 outward from opposite sides of the marker portion 26. Each 4 of the lugs 34 has an inclined upper surface which slopes downward from the side of the marker portion 26. Each of 6 the lugs 34 terminates at an outer end 38. The outer ends 7 38 are spaced apart a distance greater than the width of 8 the marker portion 26. Each of the lugs 34 has a side g camming surface 40 which is a convex curved or arcuate surface which curves toward the outer most end 38. As 11 shown in Figure 4, the side camming surfaces 40 of the lugs 12 34 are located opposite from each other, on opposite sides 13 of the marker portion 26 of the mounting core 22. opposite 14 the side camming surface 40, on each lug 34, is a flat side portion 42 located in a plane parallel to the longitudinal 16 axis of the mounting core 22. The lower surface 43 of each 17 retaining lug 34 is inclined with the lower surface sloping 18 upward from the end 38 of the lug 34 to the marker portion 19 26 of the mounting core 22.
21 A tubular marker post 44 having an elongate central 22 opening or cavity 46 is formed from a substantially 23 resilient polymeric material. The central cavity 46 is 24 defined by a cavity wall 50 which is provided with a pair of apertures 48 located near the lower end and on opposite 26 sides of the tubular marker post 44. The apertures 48 27 extend through the walls 50 of the tubular marker post 44 28 and are elliptical or oval in shape with the longer 29 dimension being parallel to the longitudinal axis of the marker post 44. As shown in Figure 4, the tubular marker 31 post 44 has an elliptical or circular cross section. When 32 the marker post 44 is mounted to the mounting core 22, the 33 retaining lugs 34 are received within the apertures 48.
34 This effectively secures the marker post 44 to the mounting core 22.
21487~1 1As shown in Figure 2, a flexible elastomeric sleeve s2 2having a lower end 54 and an upper end 56 is provided with 3an opening 58 (Figure 5). The opening 58 in the flexible 4sleeve 52 is configured to closely receive the mandrel 18 5of the base 12 and mounting portion 24 of the mounting core 622, vith the upper end 56 of the sleeve 52 receiving the 7mounting portion 24 of the mounting core 22 and the lower 8end 54 of the sleeve 52 receiving the mandrel 18 of the 9base 12. Fasteners 60, such as rivets or bolts, are used 10to secure the lower end 54 of the flexible sleeve 52 to the 11mandrel 18. The fasteners 60 are inserted through holes 62 12and 64 in the sleeve 52 and mandrel 18, respectively.
13Likewise, fasteners 66 are inserted through holes 68, 70 in 14the sleeve 52 and mounting core 22 to secure the upper end 1556 of the sleeve 52 to the mounting portion 24 of the 16mounting core 22. As shown in Figure 2, a clearance 74 17exists between the lower end of mounting portion 24 and the 18upper end of the mandrel 18. The mounting core 22 is thus 19flexibly coupled to the base 12.
21The marker post 44 is mounted to the mounting core 22 22as follows. With the marker post 44 initially removed from 23the mounting core 22, the lower end of the marker post 44 24is positioned over the upper end 32 of the mounting core 22 25with the longitudinal axis of the marker post 44 being 26substantially parallel to the longitudinal axis of the 27mounting core 22. The mar~er post 44 is then lowered so 28that the mounting core 22 inserts into the central cavity 2946 of the tubular marker post 44. As the marker post 44 is 30lowered, the lower end of the marker post 44 contacts the 31inclined upper surfaces 36 of the lugs 34 so that the 32cavity wall 50 of the marker post deforms from its initial 33configuration and expands over the lugs 34. The marker 34post 44 should be oriented so that the apertures 48 are 35aligned with the lugs 34 when the marker post 44 is lowered 21 1~7~1 1over the mounting core 22 so that they are received within 2the apertures 48 in the cavity wall 50 of the marker post 344. When this occurs, the lower portion of the marker post 444 is restored to its initial configuration with the lower 5end of the marker post 44 resting on or adjacent to the 6guard member 28 which divides the mounting portion 44 from 7the marker portion 26. The marker post 44 is thus 8effectively secured to the mounting core 22. If the 9tubular marker post 44 is pulled upward along lines 10generally parallel with the longitudinal axis of the 11mounting core 22, the inclined lower surface 43 of the 12retaining lugs 34 will contact the lower edges of the 13apertures 48 preventing dewunting of the marker post 44.
16When the marker post 4~ is struck, the marker post 44 17and mounting core 22 pivot from their original position at 18the flexible element 52 to a deflected position, as shown 19by the dashed lines in Figure 1. The mounting core 22 20gives the marker post 44 a desired stiffness so that the 21marker 10 bends at the flexible sleeve 52, approximately at 22the clearance 74, instead of deforming the marker post 44.
23The flexible element 52 then restores the mounting core 22 24and marker post 44 to their original upright or undeflected 25position.
27To remove the marker post 44, the lower end of the 28marker post 44 is rotated around the longitudinal axis of 29the mounting core 22. This causes the side edges of the 30apertures 48 in the cavity wall 50 of the marker post 44 to 31slide along the side camminq surface 40 of each of the 32retaining lugs 34. The camming surface 40 of the retaining 33lugs 34 causes the cavity wall 50 of the marker post 44 to 34be deformed so that the apertures 48 are forced away from 35the retaining lugs 34 and the ends 38 of the lugs 34 locate ~8751 ') 1 within the interior of the cavity wall 50. The marker post 2 44 is pulled and slipped off the mounting core 22. A new 3 marker post can then be mounted over the mounting core 22 4 as previously described.
6 The marker of the invention has several advantages.
7 The marker is flexible so that when struck it may bend, 8 thereby reducing any damage that would otherwise occur to 9 the mark post or marker post assembly. The lugs on the mounting core allow for a marker post to be easily 11 positioned and mounted to the mounting core by merely 12 inserting the mounting core into the marker post so that 13 the retaining lugs protrude through the apertures in the 14 marker post. The marker post is easily removed from the mounting core by merely twisting the lower end of the 16 marker post and pulling the marker post from the mounting 17 core.
19 While the invention has been shown in only one of its forms, it should be apparent to those skilled in the art 21 that it is not so limited, but it is susceptible to various 22 changes without departing from the scope of the invention.
